Problem with calibre RVE Highlights

Hi everyone.

I'm having problems when selecting and error in calibre LVS RVE, and I trying to delete the highlights with F4 or toolbar option.

Everytime I try it, I get this error.  And I have to restart everything to make it work for a while.

*Error* geDeleteAllProbe: destroyed window:  - window(invalid):629808608(destroyed)

I know this can be an error from Calibre-SIEMENS, but maybe someone have experience the same error.

virtuoso version 6.1.8-64b

sub-version IC6.1.8-64b.500.22
