I can no longer copy and paste between applications unless both applications are open at time of copy. E.g. If I PrtSc> then open Word and paste I get small unrecognisable picture. If I first open Word (then minimize) then PrtSc> (then maximise) and then paste it is OK. I have tried restoring to previous time when I new this quirk did not occur to no avail. I have been trying different firewalls and virus protection software (all now removed without any change)and I suspect one of these caused the problem. I am running XP Home on Sony FX705 Laptop. HELP!
