I have an issue where the 16x16 bitmaps in an imagelist get corrupted and are displayed as monochrome black and white images. This tends to happen between sessions in the IDE, so that after saving the project to disk, exiting the IDE, and opening up the project once again, lo and behold the images have transformed! This requires rebuilding the imagelist and is very annoying. A before and after example image is attached.
This project is being developed (and shuttled between) WindowsXP and Windows 7 x64 using Delphi 4, which is installed on both operating systems. The problem occurs rarely in XP and frequently in Windows 7. Does anyone have a clue as to what is going on here?
