Hints that may help...
If you experience problems with a Logic Café page: this may mean that the directions are not clear enough or that the web page contains a "bug". Please let me know at firstname.lastname@example.org. But it may also mean that the page did not download properly. If you are working online, just click the "Reload" or "Refresh" button to get a new copy of the page on your computer.
If you have a copy of Logic Café permanently residing on your computer everything will work much more quickly. Just go to the "downloads" option on the home page.
To print a Café page, you may want to select a "frame" by clicking it with your mouse pointer. Only the selected frame will print. If you're not sure what a frame is, check out the Web help page. (You may also be able to choose "print preview" to see what will print.)
Learn to use keyboard shortcuts. You often don't have to use the shift-key. Sometimes you can get the Café to anticipate what you need to type and do it for you.
Learn to have more than one browser window open at a time! That way you can switch back and forth between notes, reference manual, tutorial, and exercises.
Demonstrations will show you how to do logic exercises. They often run quickly; when you need to pause one for closer inspection, just place the mouse pointer over the sign. If you click the stop sign, you'll stop the demonstration altogether and go to its end. From that point you can move on to the next web page or replay the demo. Check it out.
