Hey - I'm loading DIFFMERGE with these two files attempting to compare them and every time DIFFMERGE just hangs.

I've had to go back to WinMerge to compare them - and they are only text files.

I've attached them here in case this helps.

Yeah, the files take forever to load when the Detail Level is set to "Lines and Characters". If you set the Detail Level to "Lines Only" (using the Options Dialog) they load in very quickly.

The problem here is that the 2 files (one ~64kb and one ~470kb) have nothing in common, so in "Lines and Characters" mode, the "multi-line-intra-line" analysis is getting overwhelmed.

When that is turned off, DiffMerge will see it as a "relatively simple" ~900 line vs ~8000 line comparison.

I probably need to add something to automatically detect this and back off the aggressive intra-line stuff.... [I'll add a work item to investigate this.]

hope this helps,
j
