The most consistent bug I encounter in Daz Studio (4.8 at the moment): crashing after right-clicking in an "open file" dialog.
To reproduce:
Start DS
Load several items
Do something that opens a windows explorer window (i.e., looks for a file, e.g., saving scenes)
Right-click on a folder in the window
Instant crash
If it doesn't work, don't worry - it will next time.
This happens A LOT. I'd stop right-clicking on folders in the window, except it's a habit by now. I suppose I'll get the hang of copy-pasting from the address bar eventually.
