I know this question may be seen as a duplicate with this one. I even have almost the same configuration (PostgreSQL 9.1.3, pgAdmin III 1.14.3, 32 bit Windows). What is the difference and the reason I ask a new question is that my PgAdmin doesn’t crash always (just mostly) and that the cause of the problem is different – in linked question the problem was with missing adminpack, but I have adminpack installed and it works well, so the answer for linked question doesn’t work for me.
Do you have any ideas where the problem could be?
EDIT: PgAdmin doesn’t crash at other occasions (well, unless I do someting that obviously deserves a crash), just while trying to open SQL query window. It’s worse and worse as time goes on, now it’s almost “always”. The problem is not “connection specific” – frequence of crashing is the same for different server connections.
EDIT2: I reinstalled PgAdmin and nothing have changed. I’m starting to suspect PostgreSQL 9.1.3 or even PostGIS 2.0.1 of the problem.
There can be a great many different possible reasons for crashes. Some of them have been fixed in the latest version 1.16.1, release just last week.
You could try the new version and see if that fixes your problem.
