Hi,
Whenever I search on google for UI toolkits and multithread I got always
the same result, none of them are thread safe. Windows or Linux.
Although the scripts can run in different threads (Windows or Linux) they
are using the same context to create elements and process messages. If this
is what you are doing, then I guess you will have problems even if it is
working in Windows now. The recommendation for multithread applications
(scriptable or not) is to keep UI code in the main thread always. This
seems to be a rule for any UI toolkits.
Best,
Scuri
