I frequently use online meeting software to meet with customers. Typically, I will host a meeting using Webex and have the client share his computer. I'll then take control and work remotely using an assortment of programs - Visual Studio, SQL Server Management Studio (SSMS), a browser, etc. This technique has worked wonderfully for the past couple of years.
However, I have a new customer for which we've noticed some odd (and repeatable) behavior. The problem crops up when using Webex launched from my computer or GoToMeeting launched from his. In short, when he shares his desktop and I take control I am able to move the mouse and use the keyboard just fine when IE has focus, or notepad, or Windows Explorer. But as soon as I switch to either Visual Studio or SSMS, my control is abruptly ended. Moving my mouse or using the keyboard no longer registers on his desktop. The customer can switch focus to some other program (like IE) and then return control to me, but as soon as I go back to VS or SSMS - bam - it happens again.
Note: After switching to VS/SMSS I can still see the client moving his mouse or switching windows, so it's not like the entire session freezes - rather, just my control of the remote computer seems to be terminated and not returned until my customer moves to another window and tells the screen sharing program to give me control again.
If it matters, the customer is using Windows Vista with all of the Aero bells and whistles turned on.
Has anyone seen or heard of behavior like this?
