On the note on the bugs/glitch i mentioned here supposedly there is a new version, 6.5 with bug fixes so i am downloading that now and will see how that goes.
I just downloaded the most recent version (v1.6.1), (i was checking the recent edits as usual, and decided to view all the models that are being made) so i will see how that goes.
I also deleted the 32 bit version, which i also installed sometime. There may have been an issue with the 64 bit and 32 bit competing? Either way it saves disk space too.
