uVision 5 crashes/freezes when closing

Hello All,

I am trying uVision MDK-Lite Version: 5.12.0.0. for first time. My PC is running Windows XP. uVision seems to freeze very frequently when closing down. It must be forced to close and offers to send an error report to Microcoft. On next opening, an information box opens up with following text:

! uVision has not been properly closed due to code completion.
Functionality will be deactivated until next start.

I have seached Keil website and Forums for information on these messages but did not find anything.

Thanks in advance for any information or help,

John O'Connor
