Thanks for that! We've made a change to hopefully prevent the crash.
If you can get the delay to happen again, you could make a manual process dump and email it to crashdump@gpsoft.com.au, so we can try to work out where the hold up is coming from.
Slight variation this time: filtered, selected, and opened the yellow folders in tabs, but then moved the original tab via
Go CURRENT NEW
Go TABCLOSE
to a new lister. The tab opened fine in the new lister, but the old tab wasn't closed and instead showed the "Reading folders..." message. Tab could easily be closed manually.
I've sent the dumps to crashdumps@gpsoft.com.au.
