Hi,

I have a very strange problem here, were CQRLOG hangs during many operations like upload/download from LotW / EQSL and also during updates of log-entries in contest mode. (this is not yet confirmed to be the same issue, though, but shows the same locking) The last working import / export I did was on 2025-07-08.

I am using / have tried the following:

Mint 22.2, Lazarus 3.0 (from official Mint distribution repositories), cqrlog 138 (compiled by me) / 138 (compiled by OH1KH) / 139 (Compiled by me)

2.5.2 from the official distribution repositories opens with an access violation. This could of course be the same problem, as this also locks up CQRLOG.

Trying to narrow down were this happens it is when this is called:

Application.ProcessMessages;

As this is a sort of cooperative multitasking I first thought that something locked a thread, but then more people should have seen this... Now it more points towards that there is a bug in a library somewhere, but WHICH???

Which is the recommended Lazarus?
