I don't use Robolab, but I can offer some insight into how the RCX firwmare operates with subroutines (and events) that may partially explain your problems.

Is there a bug database for Robolab? Unless it's the first perfect program ever written, there have to be bugs. Is there a procedure in place to report suspected bugs? Are they being cataloged, hopefully in a searchable database? (22 years ago, 28-Dec-03, to lugnet.robotics.rcx.robolab)
