Difficulties in loading QM2.4.3.1

[newuser]

You aren't the only one found out, the qm.exe process is running but no qm popup screen. In my case, even if I taskkill the qm process, and run it again, it still won't run.

But the funny thing is qm 2.4.3.0 works fine for me. Is there any difference between qm 2.4.3.0 and qm 2.4.3.1?

Thank you.
