Java Update 2 (released September 24, 2008) fixes this issue. Please install Apple's Java for Mac OS X 10.5 Update 2.
The "Cage Drag and Drop" functionality in the Cage View is not working correctly under OS X 10.5 / Leopard. We will address this in a future release. The temporary fix is to either (a) drag and drop individual mice to the new location or (b) make a different window such as 'List View' active. See the demonstration in this short video (requires QuickTime)
There have been reports of errors when attempting to create pups in a breeding cage that contains a male and more than one female. The most consistent fix is to set the cage status to 'idle' and than reset the cage status to 'breeding' before trying to add the new pups.
The "delete rack" function (Cage View) may give unexpected results. The function was designed to place any live mice on the uncaged list and then delete the selected rack. We do not recommend using this function if (1) you have (or had) more than one Cage View window open during the current session or (2) if any of the mice on the rack are already set to be sac'd. If you receive an error message or experience problems try placing any live mice on another rack (or directly to the uncaged list) before you delete the rack.
Remember all changes need to be recorded and updated on the server. Wait for an operation to update before you try the next operation (especially true if you are not on a fast connection). Try using the Refresh button.
