RapidWeaver 6.3.4 (with Stacks 3 and Mac OS 10.11.1) has been working smoothly until yesterday when RapidWeaver became extremely slow to open. Just opening the application (i.e. not clicking on a project file to open it) took about 5 minutes and was then so slow to respond that it has become unusable. I’ve discovered that it is now filling c. 2GB of RAM (4GB are installed — the maximum for my 2007 iMac).
Advice please. Could the RapidWeaver app have become corrupted?
