ArcMap crashes on Close with custom toolbar

[OlivierVoyer]

Hello,

I've created a custom toolbar for ArcMap 9.2 32- bits on Windows 7 64-bits that works very well. The problem is, when I close ArcMap, I receive a Run-Time error message that pops up then disappears. If I look in the Event Viewer I find this message:

Faulting application name: ArcMap.exe, version: 9.2.0.1324, time stamp: 0x452f1cc3
Faulting module name: ntdll.dll, version: 6.1.7601.17725, time stamp: 0x4ec49b8f

Any idea what I'm doing wrong?

Problem solved. I noticed the following error when closing ArcMap: R6025 Pure Virtual Function Call. I found out that many COM objects in my project were not released properly. I used ComReleaser.ReleaseCOMObject(myObject) and eveything is fine now.
