Arduino 1.0.5-r2 issue

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

The development team might not read this. I think you should report bugs on Github.
Version 1.0.5r2 is an older version, use 1.0.6 or 1.5.8 BETA.
To delete a project, use the delete project from the drop-down menu in the Arduino IDE.
Or delete that project folder if the Arduino IDE is not running.
