But in general, as I noted, ActiveX controls can be rather flaky, despite nominally looking nicer and being more full-featured than Form controls.

That's what I'm using too (to be precise, build 11330.20014).ĪctiveX controls were badly broken in Excel 2007, which was more an issue with Office 2007 rather than ActiveX, but by SP2 they weren't quite so bad. Sorry, I missed the reference to Office 365 in the subject line.
