This might sound ridiculous and I can’t find anyone reporting the same issue, but SU has suddenly started working really slowly and struggling with everything I try to do - even selecting/deselecting parts of my model, rotating etc.
Earlier today I was working on a model and all was working perfectly, when I realised I still hadn’t got around to configuring any keyboard shortcuts. I went into my preferences and added around 5 keyboard shortcuts for things I use a lot, such as, zoom extents, hide/unhide etc. When I resumed working on the same model (I didn’t close and reopen SU) everything was suddenly really laggy. It seems ludicrous that the two things could be related, but it was quite strange that it happened immediately after. Any ideas?!
