I may be able to work around this issue but I should inform the development team what I have noticed with the above Arduino version:
When using "Save As.." file function on my Windows 8.1 and consequently attempting to delete an other file/folder before pressing Save, Arduino stops altogether. I can not use Alt F4 to kill the session, Task Manager is not listing the process, nor can I cancel or close the windows on these session. My only option to rid of the dead session is to restart my PC.
Regards
