MultiPar 220.127.116.11 always shows the Repair button active, even when it says there's nothing to repair (after a verification).
You seems to be a QuickPar user and switch to MultiPar recently. The behavior is intended in MultiPar GUI by a historic reason; there were two buttons "Verify" and "Repair" at very old versions. When "Verify" button was removed, "Repair" button needed to be always active to re-verify again. At that time, there was no short-cut key, and "Repair" had a same usage as "Verify" button. Now because GUI has "F5-key" to re-verify again, users don't need to push "Repair" button to re-verify.
Though I just leave the old action in MultiPar GUI, it looks odd for QuickPar users. I will change the behavior to be same as QuickPar in next version. That may be easy to understand.
I couldn't find a bug tracker for MultiPar
This forum is good to public a bug/problem/request. Other users can know what is known incident and is being fixed/implemented. Sometimes when the bug is very complex or hard to test on my PC, I ask the poster to send the report(screen-shot, log, etc) by mail. Then, I will send him a sample version for confimation or test.
