I had that problem a few times and I saw on a forum a way to fix this problem.

"In your Fallout directory find the fallout.cfg file and open it with
Notepad.
Note: Your file may look slightly different from the one listed below.

[system] <-----look under this paragraph
art_cache_size=130
cdlock=C:\Programs\mIRC\download\cdlock.dat
color_cycling=1
critter_dat=C:\Games\BlackIsle\Fallout2eng\critter .dat
critter_patches=C:\Games\BlackIsle\Fallout2eng\dat a
cycle_speed_factor=1
executable=game
free_space=20480 <---------- find this line and change the value to 0(zero)
hashing=1
interrupt_walk=1
language=english
master_dat=C:\Games\BlackIsle\Fallout2eng\master.d at
master_patches=C:\Games\BlackIsle\Fallout2eng\data
scroll_lock=0
splash=3
times_run=5

If you can't find the line, just add it under the [system] header."
