SYMPTOMS

If the navigation arrow keys are used to try to change the Image size of icons when there are pictures already stored in the Image List property page, the user correctly receives the following error message:

"Property is read-only if imagelist contains images"

However, closing this dialog by pressing the OK button causes the message box to reappear. This behavior continues in a loop until Microsoft Visual Basic is terminated.

NOTE: This only occurs if the arrow keys are used in an attempt to change the image size.

STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. This bug has been fixed in Visual Basic 5.0.

MORE INFORMATION

Steps to Reproduce Problem

Start a new project in Visual Basic. Form1 is created by default. Add an ImageList control to Form1.
Choose the ellipsis (...) button adjacent to the Custom property of the control. Select the Images tab, click the Insert Picture button, and select any picture file.
Choose the General tab in the property page and use an arrow key to select an image size. The following message box will appear:
"Property is read-only if imagelist contains images"

Pressing OK causes the message box to reappear in a loop, and Visual Basic has to be shut down from the Windows Task List.
