Dear Rony, I cannot help you finding the cause of your problem but I can try to run the program on various machines and collect some stats. I have downloaded the complete kit and can launch startTestProgressBar.rex I can see that the rexx program launches Java and the GUI show up with 3 button

Memory in multihreaded programs should be strictly guarded. I know of a few debuggers that can set memory modification watches/traps, one is OS/2’s kernel debugger and the other is MVS’s SLIP SET trap mechanism. From what I see sometimes the register save area is clobbered (assuming you are link

One hint: after installing BSF4ooRexx one can use the menu "BSF4ooRexx -> Samples" to get an explorer window. Then changing into "JavaFX" and loading "index.html" will explain how to run those JavaFX nutshell examples. You will see why I think it is so important to get the JavaFX support stable

Hi, without going into too much detail I would say it's hard to track down the root cause just from the stack traces.

After intensive further experimentations today, on one occasion I got the following runtime-popup-error, if this matters: --- Microsoft Visual C++ Runtime Library --- Debug Error! Program: C:\Program Files (x86)\ooRexx\rexx.dll

In GUI systems the GUI maintenance and interaction are usually single-threaded. As a consequence calls to interact with GUI objects must be executed on that GUI thread, otherwise undefined behaviour may occur (usually hanging the GUI and its applications). GUI systems usually supply a utility me
