I know MD has problems with completing 1/2 completed items as of 0.6, as opposed to "string foo; foo.<CTRL + SPACE>". Does that work? Also is this *only* on files not saved? Also, what versions of gtk-sharp and gtk+ are you using? Thanks.

> Also is this *only* on files not saved?
Yes

> Also, what versions of gtk-sharp and gtk+ are you using?
dev-dotnet/gtk-sharp-1.9.2
x11-libs/gtk+-2.6.4-r1

> Thanks.
Of what ;)?

[Comment 3 Peter Johanson (RETIRED) 2005-10-15 13:24:56 UTC]

Sorry for the silence on my end. Still an issue with 0.7? If so, I'll be adding
0.8 to portage soon-ish, and we'll try testing on that too. Thanks.

[Comment 4 Aldo "xoen" Giambelluca 2005-11-01 12:13:29 UTC]

Also this other problem is solved from the 0.8 release of MonoDevelop ;)
