Ok, firstly, I doubt that this is any sort of bug, but am posting here in the hope that someone will have seen something similar and be able to suggest a solution for me.
I've, up till recently, been using build 833, then upgraded recently to 859. Things were going along fine until yesterday, when I went to open my project and couldn't. The behaviour I see is the project is left in a half opened state - the console window shows an OutOfMemoryError, and I have no sidebars in IDEA at all.
I've tried using builds 833, 856 and 859 to open this project, tried creating a new (empty) project, and even tried deleting my user preferences settings. All to no avail.
Has anyone seen something similar with this? I'm really struggling to think what it is I've done.
