QGIS 2.01 on Windows 8
I have a polygon layer which I edit in QGIS 2.01. Editing (cutting, deleting, editing new polygons with attributes) works fine. I am saving the changes after every edit or so while in edit session. Then after editing away for some time (10 Min) and saving 4-5 edits the saving process becomes unbearably slow and it takes between 1 and 7 (!) minutes to save the changes. Mouse cursor is going crazy, CPU and ram are maxing out. Then after the edits are finally saved, ending the edit session again takes several minutes. I tried the dataset with SQLite and shp, both delivered the same experience.
Any clues why this might be the case? Thanks for your help.
