"double click + ctrl key" on the icon.
logical as hell ... no?
there was a discussion about this just the other day, but i don't remember where it is.
Ctrl+DoubleClick on an item to bring up the familiar dialog. There are other threads here if you want more detail.
Found my own answer, I suppose i should have searched harder in the begining. Maybe this will help still help someone with the same issue.
I'm not sure how to link to it, but it's in Solution ID S-045011
"In the SolidWorks File, Open dialog, the "References" button allows users to change the referenced files of a drawing or assembly. Prior to SolidWorks 2009 SP5 and SolidWorks 2010 SP1, double-clicking on the name of a referenced file launched the Windows browse dialog to allow the user to browse for a replacement. Due to a change in SolidWorks 2009 SP5 and 2010 SP1 double-clicking on the name of a referenced file does nothing. This is a software issue reported to the SolidWorks Development team under SPR 528194.
Temporary Workaround: Ctrl+Double-Click
Resolution: A hot fix is now available and attached to this Knowledge Base Solution.
HotFix_528194_2009.exe should be applied to SolidWorks 2009 SP5.
HotFix_528194_2010.exe should be applied to SolidWorks 2010 SP1.
Once the hotfix is applied, the Browse dialog can be opened by selecting then double-clicking the cell.
To implement the hotfix run (double click) the program "HotFix_528194_2009.exe" or "HotFix_528194_2010.exe" when SolidWorks is NOT running. Please note that this hotfix should be uninstalled from Add/Remove Programs (Programs and Features in Vista) before applying any future service pack. It should be listed as "SolidWorks Hotfix 528194".
Note: Please verify the Task Manager and make sure that sldworks.exe is not running in the background which could cause the error message "Failed to Patch Specific Product". Killing the process and rerunning the patch works fine."
You can also triple click it! It does the same thing as Cntr+Doubleclick.
Next we will have different functions for every command, based on how many clicks we do.
Double click on file to open it.
Triple click on file to change it's reference
Quadruple click on file to rename it
Quintuple (?) click on it to delete it.
Seems it's fixed with SP2. And by fixed, i mean, double clicking works (no control or triple click). Still not sure what the replace button is supposed to do though as it has stayed the same.
