Upon selection of the 228th file, the string indicator at the bottom of a file dialog gets blank and upon clicking "ok", the Dialog returns an empty array and error "43". The files are small ascii files with rather long filenames "PS010146981_Datataking_2nd_day.hdr" and sit in a folder that contains 14730 files.
Reducing the number of files does not influence the problem.
Changing the filepath does not influence the problem.
