Problem when using texmaker on multiple screens with mac

When I am using texmaker on OSX Mavericks, there is an issue for opening 
multiple tex files when using the multiple screens. 

I have two separate desktops on the two screens and when I run texmaker version 
4.2 on these conditions, the tex editor of texmaker does not open multiple 
files at the same time (or it opens but doesn't allow to change between these 
files). The file list button doesn't work and the editor only allows one file 
to be used at these conditions. 

I hope a work around can be introduced quickly because that is easier to use 
multiple desktops at the same time on OSX systems. 

Thank you.
