Resolve MapInfo Professional 10.x and later and performance issues editing and moving a node or object when a Raster is present

Product affected: MapInfo Pro™

Issue

Opening a packaged workspace that loads without error in MapInfo Pro v12.0.0.3.
The workspace was opened on a different user's machine.
When the second user makes a table editable and tries to create, move, or delete an object, MapInfo Pro hangs
for several seconds.
Just trying to select the editable option in Layer Control also hangs MapInfo Pro as well.

Cause

The original user who created and packaged the workspace had set Image Processing for Rasters to "Always".  This setting was written into the workspace file.

UPDATED: August 30, 2017

Go to map>options>image processing and set processing to "never" and re-save the workspace.
This should resolved the issue.

When image processing is set to "never", all vectors will temporarily warp or transform to the raster's projection.
For the other 2 options, the raster will "rubber sheet" to the vectors.

Reprojection Options

During the raster reprojection process, MapInfo Professional recalculates the pixel values of the source image to make them display correctly in the destination image. In this resampling process MapInfo Professional tries to restore every pixel value of the image based on the pixels around it. In MapInfo Professional there are two methods for calculating the pixel values of the destination image: Cubic Convolution and Nearest Neighbor. These are industry-standard terms used by GIS professionals all over the world.

Never

Select this options to indicate that Raster images should not be reprojected when added to a vector map and presents raster reprojection. This is the default setting which preserves the pre-version 8.5 MapInfo Professional behavior.

Always

Select this option to ensure that reprojection is always performed, that is, MapInfo Professional calculates the image's coordinates based on a precise formula and then the pixels are resampled using Cubic Convolution or Nearest Neighbor options.

Optimized

Select this option to ensure that raster image reprojection is determined by the look of the destination rectangle after transformation into the source image space. If it looks as a rigorous rectangle (two sides are parallel to x-axis and two sides parallel to y-axis), then the standard Windows functions stretch the source image in both directions as it was in pre-version 8.5 MapInfo Professional. If the image fails the rigorous rectangle test, the reprojection is performed using the specified resampling options.

Resampling Method Options:

Cubic Convolution

Cubic Convolution provides the best "restoration" of pixel values because of their discreetness. Using this option, a pixel in the destination image is calculated based on the pixel values in a 4x4 pixel window centered at the basic pixel in the source image. The coordinates of the basic pixel are calculated for every pixel of the destination image based on a special optimized procedure. Pixels are then weighted based on the basic pixel coordinates. In general, we recommend you use the Cubic Convolution resampling method for aerial images and satellite rasters to get a better image quality. The Cubic Convolution algorithm used in MapInfo Professional is based on the work of S.K. Park and R.A. Schowengerdt, Computervision, Graphics and Image Processing (1983, Volume 23. Pages 258-272).

Nearest Neighbor

Nearest Neighbor replaces the pixel value in the reprojected image with the basic pixel value from the source image. This resampling method takes less time to render than the Cubic Convolution method, but may be less precise. In general we recommend you use Nearest Neighbor resampling for raster maps, grids, and scanned maps to get faster results.
