Uncorrectable error has occured

I have an user that gets the following message while their client is open:

Sorry, an uncorrectable error has occurred.

LookupHandle: handle out of range

Press Enter to abort the operation

I know this is a bug in version 6.5.3, but I need a work around until I can upgrade.

Thanks
