Hi a couple of interesting things here
I am using XP sp3 so DOS is more correctly the command line window I suppose.
Lazarus IDE problem - solution I was using the komodo antivirus suite when I removed this and replaced it with a different antivirus program (I have digital defender installed at the moment), the problem went away.
The fp.exe ide which has been givining problems (under this xp installation) is the one take from the current DOS version of free pascal.
(\bin\go32v2\fp.exe)
After searching my hard disk, I found a version of fp.exe which came with free pascal compiler 1.10. This runs OK. I placed it in the folder:
C:\lazarus\fpc\2.2.4\bin\i386-win32
However it fails to compile since it cant find the basic units.
Maybe this can be set up to find the units?
