Hello
I tried it, on the desktop, and get the same error.
Steps:
1. new project
2. saved the project in directory TestProject
3. in the Designer, added an ImageButton to the form
4. in the Designer, loaded an image from another directory Bitmaps
5. the designer copies the image file to the TestProject directory
6. in the Designer, added a second ImageButton
7. tried to lo load the same Image file, as for the first ImageButton, from the Bitmap directory.
in this case the error happens.
for step 7. we must load the image file from the TestProject directory
The error happens when we try to load an image file that already exists in the project directory from another directory.
It would be nice, instead of getting an error, that the Designer checks if the image file already exists and changes the directory itself.
Best regards
