original ibook problems with Skype

My daughter has an original ibook (g3 500mhz), with 256k memory (2 128mg modules, I think). She is having problems running the latest version of Skype (1.4 -with video) - it just doesn't run - no error messages or anything (previous versions ran just fine).

Is this a common problem? Any ideas on what she might do to fix it? I was wondering if more RAM might help - b ut don't know what is the maximum ram one can put on that IBOOK.

Thanks
much - any advice appreciate greatly.

This forum is not for software questions as the sticky at the top states.

Moving to correct forum...

Which version of OS X is installed? (To find out click the apple logo-> about this mac).

Run software update to make sure you have the latest version of the system (10.4.7) if it isn't installed. (Apple logo-> Software update).

In that iBook you can officially install a maximum of 640 MB (128MB are soldered onto the mainboard, you can put a 512MB stick in the other slot).
Unofficially I've heard you can add another 1GB for a total of 1128MB.

But I'd check to make sure it's not the OS first.
