Save As (on Windows 8) adds file extension twice

[sagha]

I'm using the most recent version of EqualX on an updated Windows 8.1 machine (64-bit) with 32-bit Latex. When I click File > Save As to save my equation, the file extension is added to the file name twice. For instance, file "foo" will be saved as "foo.tex.tex". Updating the file by going to File > Save As and clicking an already existing file will append another extension to turn the file into "foo.tex.tex.tex". I have only verified this with the .tex extension.
