TextMate 1.x on Mac OS X 10.5 Leopard has a problem with the Find and Find in Project windows.
- Open a TextMate window
- Open the Find window
- Open another TextMate window in a different "Space"
- Open the Find window again
- You should expect to have the Find window open in this new space
- The Find window opens on the first space and switches your active space to it
The cutting edge builds, available by adjusting software update preferences, do set the window property that has Spaces let the window open on the active space instead of last.
