Description rbrdck@firemail.de 2026-02-02 22:21:51 UTC 
Setup:

2 LO instances and their Conditional Format managers are open side-by-side, with two different version of a table with various CF rules for numerous ranges of cells.

After some time of repeated editing with copy/pasting rules (since there's no 'Copy' function in the manager) from one to the other window (which may include repeated task switching ALT+TAB), both managers can eventually become unresponsive, i. e. clicking 'edit' or doubleclick on an entry in either will not open the entries anymore (the manager can't be closed anymore sometimes and both unresponsive instances' processes need to be killed manually).

Either way, only after restarting LO and recovering the affected documents, editing the CF's is possible again.

Version is LO 25.2.3.2 (AARCH64).
