After I’ve switched to 2.80 it seems grid scroll bars are not working correctly in Win98.
Try the SimpleGrids sample in Win98 and move the vertical scroll bar.
After leaving scrooll bar it is drawn at top and not working correctly.

Thank you.

We are currently testing the scroll bars on Windows 98. Please give us 1-2 days more.

We have detected the following problem with skinned scroll bars only when running on Windows 98: when the grid’s scrollable area is small but not very small (400 x 300 pixels for example), the horizontal scroll bar thumb button is painted incorrectly, has an incorrect size and sometimes intersects with left/right buttons. We found no problems with vertical scroll bars. Please provide us with some description about any other problems with scroll bars you faced when the app is running on Windows 98.

I’ve run simple grids in Win98 (running in MS virtual pc but I don’t think it does matter) because I have the same problem in my app where I’m using tree grid control.
Screen resolution is 800x600, I maximize the app, then click vertical scroll bar, drag it to center and release.
After I leave scroll bar area by moving pointer to client area, scroll bat jumps to top, but it is not really there, I can’t drag it again.
I cannot try it again until monday so I hope I’ve described it good enough.
Sample was using default office 2007 theme, I don’t remember whether I’ve tried it in another theme.

This message is to notify you that we are working on this problem. To make the scroll bars working on Windows 98, please add the following code into CExtScrollBar constructor:

      if( ! g_PaintManager.m_bIsWin2000orLater )
            m_bCompleteRepaint = false;

scrolls are working now but scrollbars are drawn using old theme (I guess you know about it)

This is just a temporary solution which should let you test your application on Windows 98.
