Cannot open folder with right click meny in Transfers

[zoran djurkovic]

Hello,

Sls QT2017 2.20, on Win 10 updated to the last official update.

Suddenly I cannot open folders with right click in transfers tab.

Do you know the solution to this problem, please.

The other 

question would be:

If I update my version of Qt to the last one, will it erase all data and settings. eg. transfers, uploads, qued etc.

Thanks in advance.
