Spellcasting by clicking on the icons in the Magic Tool is slow. Why is that ?
Extensive testing by a lot of users has proven that the Magic Tool causes no noticeable delays when casting spells when the machine that runs the tools has enough available resources and/or processor speed. On a Pentium 166 MMX with 32 Mb RAM and 100 Mb free harddisk space the delay was very very small. Most of the time the only delay measurable was caused by internet lag. The only delay is the time that elapses between clicking on the spell icon in the Magic Tool and UO becoming the active window again. If you notice your harddisk is starting to work a lot in that moment then you are probably running low on memory. I suggest adding more RAM or freeing up some space if you have a very small swapfile to work with.
