Bug in VBA in Excel?

Excel VBA ScreenshotI’ve been spending a lot of time in Excel’s VBA (Visual Basic for Applications) editor and I’ve found an odd bug. In the main code editor window the scroll wheel on my mouse won’t work. I didn’t realize how much I use that scroll wheel while I’m coding, until it didn’t work.

I’m also pretty sure that the intellisense is buggy or perhaps just not that intelligent.? That’s the problem with getting so used to IDE’s like Visual Studio 2005 and the new Netbeans, is that you come to rely on intellisense and auto completion and those cool drop down box’s too much. Maybe I should go “hardcore” and use emacs or VI or cat, mmmh would have to be notepad on windows…
This is all in Microsoft Excel 2003.
