With Kstars 3.3.6 I am unable to save new sequences in the capture module. Has something changed that I did not catch? This happens on systems running Ubuntu, Arch Linux, and Stellarmate. After I create a sequence I can see the .esq file, but when I open it the sequence is blank.
I just tried this with KStars 3.3.6 on Mac. No problem what so ever to create an esq file in the Capture tab, nor an esl file in the Scheduler tab. Can you create a screenshot prior to saving the job in the Capture tab so we can try to reproduce your issue?
Another silly question: are you sure you have disk space left? I just tried this with KStars 3.3.6 on Ubuntu 19.04 and I can create job files that contain XML data.
The screenshot labeled before is just before saving. destination is after hitting the save button. After-saving shows the saved .esq file. After restore show after opening the saved .esq. My issue is saving creates a named empty file. I have several hundred gigs of storage available. This happens on three different computers. I downgraded my Arch Linux box to 3.3.5 and it does not happen.
There is a strange character in the FITSDirectory name. As soon as I remove that, it opens fine. Please try to avoid special characters in paths and limit yourself to the first 127 ASCII characters. I have attached the working file.
