Thanks for the update. I have updated Enpass on both laptops but unfortunately the issue is not resolved. Following is the information you asked for;
1) Yes the issue occurs on both laptops. What do you mean by their version? Both are running windows 7, 64-bit system, i5. Brands are HP & Toshiba.
2) Antivirus is Trend Micro OfficeScan 12.0.5383 which is installed only in HP laptop. Toshiba laptop does not have antivirus.
3) Admin user in Toshiba. In HP guest user but I had login as admin and still the same.
