I tried to install my VFP 9 application in a number of computers running Windows 98.

I have a custom toolbar based on the VFP toolbar class.

Problem:

Application toolbar is not visible when docked to the top or bottom side of the screen.

Toolbar area is not updated and does not respond to mouse clicks. If I switch to other and then back to my application, toolbar area shows contents remaining from other application screen.

If toolbar is not docked or docked to the left or right side in the screen, all is OK. This problem does not occur in VFP 8 . It occurs also with VFP 9 toolbars when running VFP9 under Windows 98. I tried to use gdiplus.dll from VFP8, but this does not help.

This problem is critical to me. How to fix this ?
