Running:
Excel 2007 (12.0.6654.5003) SP3 MSO (12.0.6607.1000)
Fire Fox 11.0
Skype 5.8.0.158 with click to call

With Fire Fox running, paste special does not work
With Fire Fox off, paste special works
With click to call disabled in Fire Fox and Fire Fox running, paste special works.

A very strange 3-way interaction. I suspect that Skype is the culprit here. Can't prove it though. Updated Excel, Skype and Fire Fox all on the same day.

Anyone else have any thoughts on this? Any chance someone is having this problem without these three programs running?
