Changing the undo size
Xara LX uses memory to store a list of all the operations you have performed so it can undo them. You can set the undo so it is unlimited in size, or limit it.
To change the undo size
1. From the Utilities Menu, choose Options.
2. Click the Tune-ups tab (see Tune-ups Options).
3. Select Unlimited Undo Size or click the Limited Undo Size button and enter a maximum size.
Tips
You can enter values in megabytes, kilobytes or bytes. For example "1M" (1Megabyte), "200K" (200 Kilobytes), "4000" (4000 bytes).
When the undo buffer is full, the oldest information is discarded first.
