I have Maxima 5-19.2 installed on a Dell precision 6300. I can't even run it from the command prompt (I tried). Wxmaxima crashes even when i try "report a bug". I played with Dep settings and Zonealarm, but no success. Yes, it has been downloaded from sourceforge.net. Strangely enough, I have two more Dell laptops around the house (older models, one windowsxp and one windows2000) and on those it runs fine.
