Symptoms
When using a CoolBar control, your compiled application hangs or generatesan exception error or invalid page fault (IPF.)
Resolution
An unhandled error occurred in one of the CoolBar’s Events.
Symptoms
If you have a Visual Basic application with a ComboBox control set on a band of the CoolBar control, it works as expected in versions of Visual Basic earlier thanMicrosoft Visual Studio 6.0 Service Pack 4 (SP4). However, if you are using SP4, the application may stop responding (crash) when the form that hosts the CoolBar control closes. The crash only occurs on systems that are running on Windows 98 or Windows 95.
Resolution
This behavior occurs because the controls set on the band of CoolBar are not cleared at the correct time.
