Per the Technote below, I installed ST 7.5.1 CF1 to correct the 'Joining the Meeting....' hangs some users experience when attempting to join a meeting. The Hotfix seemed to correct the problem for some, but there are still users experiencing this. The JAVA console indicates they are having the exact issue this fix was supposed to correct. Anyone else having spotty luck with this hotfix?
I plan on calling Lotus later today to open an incident. If I get a resolution I will update this post.
