Hi,

So I have this problem for a long long time. Just now it got on my nerves and I decided to try and do something about it.

The PLSQL Developer Freezes a lot during the day. Each freeze lasts about 30 seconds to even 2 minutes.
The freeze seems unrelated to anything, It can be on query submission, on simply switching windows, on copying text, on invoking auto complete, on starting up explain plan, on clicking any button really. it seems to happen on random events sometimes unrelated to network, querying, CPU or anything.
Video example of a freeze during explain plan startup

And its not that the DB is slow, the plan takes time or anything. if I use Toad for example that plan would take 2 seconds to come back.

Can this problem be solved?

thank you!

I see that this happened in the video when opening a new Report Window. The Report Window has appeared, but it is not yet displayed in the Window List.

Can you go to Help > Support Info and send me the information from the "Info" tab page by e-mail? We can then send you instructions to obtain more diagnostic information.

To obtain some more diagnostic information, can you modify the PL/SQL Developer shortcut and add the DebugSQL parameter? For example:

"C:\Program Files\PLSQL Developer 13\plsqldev.exe" DebugSQL

Reproduce the problem and send me the debug.txt file that is generated in directory "C:\Users\G520844\AppData\Roaming\PLSQL Developer 13".

I have a bit different problem.
1. When the PLSQL Developer Freezes It freezes also the whole desktop. I'm unable to click on any other program. When ver. 14 was freezing (due to recompiling many objects on base) then I could switch to another program. Now the whole Windows freeze. Looks like ver 15 is more connected with widows.
2. When I minimize and then maximize the PLSQL Dev it first shows black widows, then it begines to slowly refresh widows. It takes from 2 seconds to 10 seconds. Looks like that the longer it is PLSQL Dev out of focus the longer it takes to reassembe it. My computer is a few years old but quite strong, it should work better.

I experience point 2. of @matejj everytime PSD is minimized. The redraw of PSD when maximized takes couple of seconds showing black ribbon and SQL zone.

My colleague reported freezes in PLSD. We tried to remove git directories in "Files" tab and freezes are gone. Maybe it helps.

Similar hangs here, but *not* using version control in PSD.

Page goes grey and Windows sometimes asks if want to kill or wait for it to complete.

We also occasionally lose icons and names in the left-hand panels e.g Files. We can still see the folder structure, but the item icon and file name is missing. This usually proceeds a crash from PSD that generates a support email and then it gets into a loop of crashing and emailing.
