Strange problem happening today

hi there seems to be a problem when I open a blank gig file and load in a rackspace there will be no sound but it is receiving midi. The only way I seem to get the rackspaces working is by loading another rackspace in and then clicking on that one, then go back to the original one and it is working again.
I cant explain it any bett

t seems to be on any rackspace I choose.

Just tested and I can not reproduce.
When you start Gig Performer and import a racksace then you have 2 rackspaces.
One is empty and the other is the new imported rackspace.
Could it be that after import the 1st rackspace (the empty) was selected?

I have to do more tests to find out whats going on
