Here's my lashup:
1) Host: Windows 7 - 64bit running 790308. Guests: All windows of all varieties.
2) Over the network "Shared" Host: Windows 7 - 64bit running 646643. Guests / Shared: All Windows of all varieties.
Tried to connect from 790308 to 636643... Connects OK, then shared guest refuses to respond to EITHER keyboard -or- mouse. DOES respond to menu CTL-ALT-DEL. Basically, this connection becomes unusable.
Yesterday, Host #1 was running 636643. Using GoToMeeting I "gave control" of mouse / keyboard to other presenter. Worked fine.
Today, Host #1 was updated to 790308. Using GoToMeeting OTHER presenter was UNABLE to click / type inside Guest windows.
So, I had to revert my main host BACK to 646643 which immediately resolved both issues.
We will take a look into these issues. Thank you for reporting them.
