Bitmap Viewer is not saving the settings after it is closed and reopened.
Bitmap Viewer does not keep the preferences that are set when I launch it. Units and toolbars are reverting back to the default settings when I close the program and reopen.
The issue is either a corrupt preference file or permissions problem.
Delete the file C:\Program Files (x86)\BitmapViewer\viewer\ImageListStandalone.INI
If the file does not delete then the permissions need to be adjusted for the Bitmap Viewer user to have access to write to this folder. If the file deletes then the preferences were corrupt and you should be able to save your settings now.
