vSphere on WIN7 Ultimate 64-Bit console hangs after minimize

[Cr0n_J0b]

I'm noticing something strange.  I'm rather new to ESX, so forgive me if this is a dumb questions...but...

I have ESXi 4.1 running fine on my server.  I have a couple of guests, linux, windows and BSD.  I've noticed that when i open a console, and then minimize it to work on another system, it will become unavailable.  I'm using vSphere 4.1 258902 and WIndows 7 ultimate 64-bit.  The hangs are not 100% consistent, but are regular enough to be annoying.  I can see the object in my taskbar and in the toolbar, I can even see an image of it when I alt-tab, but when I try to click on it i get nothing but an alert bell.  I can close the console out and open a new one without an issue, but I'm hoping there is a fix for this or I'm just doing something dumb

thanks

I've been having the same problem with ESXi/vSphere Client 5.5.0.  Decided to Google around and found your post.  Unfortunately, the issue persists. 

My workaround is to click on the vSphere client icon in the taskbar, then close the (minimized) console window by hitting the red "X." 

After that, I just open another console (on the same Win7 VM), and I'm back.  Mildly painful though.
