I had added the following to another users question and I'd like to include it here.
I succesfully used OnLocation CS3 with my Toshiba Pentium 4 laptop with a max screen resolution of 1024x768. Based on DV Rack, the tool layout was sloppy, requiring me at this resolution to scroll down the screen for panels below the current screen. I eagerly moved on to OnLocation CS5 with its neat Adobe CS layout style. It booted up fine but the panels were squashed and I couldn't get any panel response. Bad news. Searching for a reason, I found a website that stated a requirement for a 1280x900 screen resolution (actually the complaint was from a guy with only 1280x800 resolution). Not good news. My quad desktop and monitor ran OL CS5 in fine style.
Well, I said, I'll just switch back to OL CS3 which worked before on this laptop. On startup, the app repeatedly crashed on initial panel loading. The only thing different with the setup was that I upgraded from WinXP to Win7, normally an excellent decision. I tried to use the compatibility wizard to allow Win7 to operate as a WinXP machine. No good. Microsoft has no fix for this problem. So in addition to the problems previously noted, pay attention to OS compatibility.
Thanks for your response.
This Toshiba laptop is only capable of running 32 bit programs. It's not
the CS3 installation disc because I have installed it on three other
laptops running on XP as a trial and it works fine. So the problem is
within my laptop.
Note I also have Production Premium CS5 but Win7 refused to load because
of lack of screen resolution. Based on your statement about OL CS3 on
Win7Prem below, I'll retry that install. I added XP as a dual boot
because in the past, this laptop ran OL CS3 on the preceding XP OS. I
run everything else in Prod. Prem. on a 64 bit Win7 desktop but who
wants to take a desktop to a remote shoot?
I'm also going to take the laptop over to a place with free testing to
see if they find anything wrong with the video card.
Updates for both Tosh laptop and XP are current (The latter on SP3).
