Hi,<br>
<br>
I tried to import a large *.bdf file, 614 MB. I get the "Out of memory" -<br>
message, but not on all computers and for some reason it seems as it does<br>
not depend on the actual memory. It works on a weaker system, but not on<br>
the current one, which has 3.8 GiB of memory and a Intel Core 2 Duo CPU<br>
R7500 @ 2.93 GHz.<br>
<br>
Even on identical systems with the same hardware and same software I can<br>
load the file only on one of them. I tired it with Windows XP and Ubuntu<br>
10 on the system mentioned above, no difference. Any suggestions?<br>
<br>
Thanks in advance<br>
Benjamin Kuhr<br>
<br>
