Lightroom 1.4.1 has always had a minor bug with Spaces in Leopard. Notably, in 10.5 to 10.5.2 if you switch spaces around while running Lightroom the panels may not redraw. If you do something in Lightroom they will come back. I've pretty much just gotten used to this. However, in 10.5.3 there is a slight addition to Spaces that causes a fairly frustrating bug with Lightroom 1.4.1.
This change has to do with changing spaces automatically when you command-tab between applications. It's a nice change and makes spaces easier to navigate.
Note that after installing 10.5.3 this option is enabled by default. The result that I'm seeing is as follows. This is the bad behavior.
- Start in Space 1. (I have 4 spaces configured in the default 2x2 grid)
- Launch LR 1.4.1. In my setup I have LR "pinned" to Space 3 in the spaces control panel.
- OS X switches to Space 3 and Lightroom launches as always.
- Lightroom launches into Full Screen mode (no menu bar displayed), my typical use. Everything is good through here.
- Now switch back to a space other than Space 3 (where LR is). Works fine.
- Now cmd-tab to switch applications and select LR.
- You are NOT transported to the right space, you remain in the space you are in. However, the menu bar does dissapear.
When you update to 10.5.3 just beware of this. You'll have to manually change the space to get back to Lightroom.
