Discuss any Prof-UIS and GUI development-related issues

We’re using Prof-UI v.2.82 for MFC and we’re creating a application that has user interface (UI) like RibbonBarMDI example. However our application has a bug that RibbonBarMDI example has too.

This bug is described the following:

1. In RibbonBarMDI’s main UI click “Application button” button,

2. In the file menu move mouse to “Finish” (or Share…) file

3. And then move mouse to “Mark As Final” ( or else button in Finish group )

4.And then left mouse click in blank region of main UI

--> has got error message

Unhandled exception at 0x783c04fd (mfc80ud.dll) in RibbonBarMDI-ud.exe: 0xC0000005: Access violation reading location 0xfeeefeee.

The current position pointer in debug mode as the following:

else<o:p></o:p>

return m_pCtrlSite->ModifyStyle(dwRemove, dwAdd, nFlags);<o:p></o:p>

}<o:p></o:p>

How can we fix this bug ? <o:p></o:p>
