Bug with QuickBooks Desktop login?

I have noticed that as long as I’ve used EMClient (about 2 years), it crashes if I have my QuickBooks Desktop enter password box open and type anything in the EMClient window (intentionally, or otherwise). I have to restart EMClient and wait for it to determine if my database got corrupted (which it never is). This doesn’t happen any other time while QuickBooks is being used.

Has anybody else noticed this?

Quickbooks could be using a eg: similar OS internal file like a library file or framework etc.

What version of Quickbooks is it ?

Also have you contacted Quickbooks technical support?

Also what version of eM Client do you have ?

Also do you have Windows or Mac and what OS version ?
