I believe this was fixed with commit 17811ce518f2db3db4ecb15c81ed774593715713

Can you please check that it's fixed with current master build?

Binaries are downloadable from here: https://subtitlecomposer.kde.org/download.html

Comment 5 Hilde Meuris 2022-11-23 10:36:49 UTC

Indeed, it is fixed in the latest git development version. Thank you very much.

Comment 6 Mladen Milinkovic, Max 2022-11-23 10:53:15 UTC

Great.. thank you for reporting the bug!

Comment 7 Hilde Meuris 2022-11-23 11:31:27 UTC

I just noticed that the latest git version crashes when I try to go back to the previous subtitle image during the import. This problem did not occur in 0.7.1. Should I make a new bug report for this problem or leave it here.?

Comment 8 Mladen Milinkovic, Max 2022-11-23 14:17:21 UTC

It's fine here, will fix it ASAP.

Comment 9 Hilde Meuris 2022-11-23 14:27:44 UTC

Thank you.

Comment 10 Mladen Milinkovic, Max 2022-11-23 17:00:57 UTC

That was fixed too with commit 78553af05ba97da0920f7cabd281503bd4ca484a.
Download page should be updated in next 30mins or so.

Comment 11 Hilde Meuris 2022-11-23 21:55:30 UTC

I just downloaded the latest version and it works. Thank you very much.
