Experiencing very large pauses/lag that doesn't happen with 1.6.5 with same document. Selecting, drawing, moving a layer, using keyboard nudge, all is very slow.
Im here drawing inside an embedded document that has a lot of instances/copies in root document (for effects and filters), so maybe that has something to do with it? But root document is minimized.
Hope this will get corrected before 1.7 release. Let me know if theres things/info you want me to provide. My iMac is oldish but isn't that slow and has 12gb of memory.
