Re: NDPluginFile question

[Jörn Dreyer via Tech-talk <tech-talk at aps.anl.gov>]

Hi Mark,

sorry for the long delay. It took me a while to setup a new system to do the test.
It turned out, that I did not close the file in the closeFile function. It was in there but commented out. Together with some
other code. Probably i was distracted doing some debugging because the function caused a crash when reopening a new file.
Now everything works as expected. Even the outosave function.

Thanks for the tips.

Regards

Jörn
