Trying to update to RapidWeaver 8 from 7 before moving to Catalina. So still using MacOS 10.14.6 on iMac 5k. 2 Projects open, one converted from RW7, one new (Engineering theme), only about half a dozen pages. So far only 1 PlugIn: Stacks (what would a weaver do without that ;-). On launch of 8.5.1 RapidWeaver repeately crashes with: Process: RapidWeaver 8 [1420] Path: /Applications/RapidWeaver 8.app/Contents/MacOS/RapidWeaver 8 Identifier: com.realmacsoftware.rapidweaver8 Version: 8.5.1 (20823) Code Type: X86-64 (Native) Parent Process: ???
