divide by zero/ access violation
divide by zero/ access violation
hello,
when i use the dwf importer, i get in some programs a divide by zero, than an access violation.
the call stack is as follows :
dimensionx! oddbtext::createobject(void) + 726 bytes
dimensionx! oddbmtext::createobject(void) + 349 bytes
dimensionx! dwfcallbackmanager:rocess_text(class wt_text &,class wt_file &) + 551 bytes
0012d968()
dimensionx! wt_text:rocess(class wt_file &) + 19 bytes
0012d968()

unfortunately, i have tried uploading 5 mb files before but they time out and i cannot get the file uploaded, is there any other place i can place the file (dwf file) for your use if you require it.
cheers

do you have a possibility to modify the source file? do you have a possibility to separate a problem entity or to get a file having much less size?
