Ran across a new problem with .026 - active window frame right is painting lighter than the source image, by about 20 RGB points.
The image on the left is how WB6Config previews the close button & top portion of the window frame right (correctly). The image in the middle is the source image. The image on the right is the close button & top portion of the window frame right as WB6 applies it to the active window - you can easily see the lighter hue of the two right-most pixel columns (the top portion of window frame right). Using magic pink trans.
Did not notice this until the .026 update, but could have been there before since it is subtle.
I believe all your painting issues are caused by a bug in the transparentblt support in your graphics card drivers. The drivers for early ATI boards have buggy alphablend support as well.
This would explain why it works perfectly on all our test boxes.
If you alter the hardware acceleration slider in windows (display properties->settings->advanced->troubleshoot) does the problem go away?
I dropped the slider down one notch from full and indeed the window frame right paints correctly now. So, a BIG thanks for recognizing that.
However, it didn't affect the painting issues I'm having with menus & MDI buttons - they still paint the same. With due respect, those painted flawlessly on this rig with 5.49 (even with full hardware accel) so it's hard for me to accept it is
only the ATI drivers - something about the way WB paints menus must have changed with 5.50 & up. I would love to update these drivers but they are a proprietary Fujitsu set that I can't update, even using Patje's Mod Tool. Being a notebook with integrated graphics (and my primary business rig), I'm a little leery of how forcing a change might negatively affect the system, anyway.
I'm using .tga images for the menus with only 4 trans pixels, one in each corner, in case that somehow influences your thinking on this. The MDI buttons are using magic pink trans in the areas that paint darker.
I'm very grateful for the effort you've put in trying to diagnose & resolve my issues, Neil. Wish I could let you have this box for a bit to see what you could do...
