I have just found a problem with the Dir ComboBox in ODCL 7.0.0.5 + BC 12.2.7.
The OnSelChanged event does not return a string value but something like this:
"頠\037\031\037큨\037濐ʶ\003".
I have tried to switch off Bricscad's "Fast COM" which can give similar problems:
(if lisp$enablefastcom (lisp$enablefastcom nil))
... but that did not solve the problem.
Also the problem does not occur in ODCL 7.0.0.4 + BC 12.2.7. So it must be, at least partly, ODCL related.
That's a bug introduced in Alpha 5, now fixed for the next build.
Great, thanks Owen.
