Even now a team of Evo developers is descending on your location with ketamine and dramamine. Problem with fast clicking.... solved!
 
On a more serious note, have you tried placing this as a bug in mantis?

[color=#ff0000]Dear RPCAdmin
You Are Not Alone - We feel your pain!   And no amount of good humor will make us feel any better until our programmer friends can make a fix for this.  So come on people, sign on and let them hear your cries for help on this one!

We can't precisely repeat this one every time but can make it happen often enough that we have a pretty good idea what it is.  We have a modified AR-A available to test but the price that you have to pay is that the ability to toggle between the DBA Classic screen view and the Evo tabbed screen view is (temporarily) a company-wide default setting rather than user specific.  If we confirm that this resolves the problem, then we will do the additional programming to get it back to a user specific setting.  Mike I will send it to you; if anybody else would like to try it, please email me.

It is AR-A only, and only for testing purposes.  It will be a one size fits all setting for AR-A (Classic or Evo view) but if we determine that this approach is a solution then we will add the capability for user-specific settings.
