I upgraded to Leopard on Friday when it came out. (I admit it: I even stood in line and got a free T-shirt).
I really like Leopard, but I couldn’t get widget programs in IDL 6.4 to work under it. The good news is that beta versions of IDL 7.0 seem to be just fine. Also, under Leopard, I end up with multiple X11 applications running when IDL (even 7.0) is running, so I’m not sure I have everything configured correctly (I can’t even find the system xinitrc anymore).
The best part of Leopard is that it seems to be so snappy. I have a fairly new Mac Book Pro so take it for what it’s worth, but everything seems to be much more responsive (I think Leopard makes better use of the graphics card and multiple code CPUs.).
UPDATE: It appears that using Tiger’s X11.app should fix it for now. Link.
UPDATE: ITT VIS has released a fix for this issue. See this tech tip. This works for me.

When you say “widget programs”, do you include ENVI? I upgraded this weekend as well, and although IDL (6.3 in my case) will run, ENVI will not launch (and IDL punts with a bus error). I haven’t seen anything about this elsewhere on the web (yet).

Yes, this is exactly what is happening for me with any widget program (including ENVI).

It’s good to see that IDL is responding to Leopard issues so quickly. I’m looking forward to getting the full 64-bit performance once I upgrade. Have you had any issues with that?

I’m not seeing any 64-bit issues, but X11 is still causing me occasional problems. After “a while”, widgets will just stop responding to events. I haven’t given up and reverted to Tiger’s X11 yet, but I might soon.
