Dear Joe a few days ago I asked you to change your code slightly. By some reason I had no E-mail access for the last several days. Have you implemented the corrections I was speaking about ? Didn't it help ? I've to remind that ROOT under Window is implemented as a multithread program. On other hand some pieces of ROOT are not thread safe. This means one always can write the code that will access one and the same memory simultaneously and cause the program crash. When you create your own "root-based" application you have to take this in account to keep your application thread-safe to avoid an unexpected crashes. Very likely I should explain briefly that the interactive applications like ROOT has to be multithreaded. Under UNIX there is no need for any special pre-caution since the second "interactive" thread is resided within a separate process (called "X-terminal"). By this reason the interactive X-based application may be single-thread. Windows OS doesn't provide a dedicated separate "process-terminal" to manage "widgets". WIN32 application must control its own widget alone. By this reason the ROOT (and any other application) under Windows has to create and maintain such kind of "control" thread internally. By this reason I'd like to ask you again to try applying the remedy I posted a few days ago and tell us whether it helps.
