The program locks up instead of bringing up the first dialog for adding a new feed, whether I click the big green + button, go to add a feed via the File menu, or tell Firefox to add a feed via QuiteRSS.
Once it's frozen, it beeps whenever I try to click anywhere, but I am able to close it via right-clicking the tray icon. When I close it that way, I see this as soon as the little "saving data" window goes away:
Test version (portable windows): https://yadi.sk/d/-mL1zh4gMHXwt
Still present in 0.17.4. I have a feeling it might be related to coming out of Hybrid Sleep on Windows 7, but haven't had a chance to do some tests yet.
Doing a full shutdown and restarting didn't seem to fix it, but for a little while it was working as normal. I can't pinpoint the cause.
EDIT: I figured it out. The new feed dialog was appearing in my second monitor for some reason. I discovered after noticing that if I press Alt+F4 while it was 'frozen', it became responsive again.
What is the function of ALT-F4 in QuiteRSS? Same as for Windows, closes the current window?
Yes, it is. The default behaviour.
