Different window class every launch

[pctechtv]

I am trying to add a command to bring a window (Camtasia) to the front or launch it. I usually am successful with a command like

Code:

Copy      Help

int w3=win("Camtasia 9" "HwndWrapper[CamtasiaStudio.exe;;8840f44d-1628-4e6b-a264-e2e4c072445c]")
if(!w3)
   run "C:\Program Files\TechSmith\Camtasia 9\CamtasiaStudio.exe"
else
   act w3

My problem is the application keeps changing the class. When Firefox was doing this, I was able to use an empty string. I can’t seem to figure out what would work here. When I record the macro, I pick up something like this

Code:

Copy      Help

int w1=act(win("Camtasia 9" "HwndWrapper[CamtasiaStudio.exe;;9dd82749-1bbb-46d5-af73-64f395048457]"))

however, like I said the long number seems to change every time launch the program. How could I create a string that finds the window each time? Thanks
