Looks like scala related:

messages.log

There are several reports related to SlowItem already, so I didn't want to create yet another one, even though I don't know whether it's exactly the same issue (but the others are mainly marked fixed or duplicate and this is verified on the latest nightly build of 2010-04-26).

I have increased the priority to P2 because this regression (presumedly, because I don't have previous versions anymore to verify that, but it would have happened sometime this month) is making the program almost impossible to use because of the numerous times that one has to press escape to make the dialog disappear, and because it nearly always interferes with code completion (sometimes the options briefly appear but are then immediately replaced with the report that pops up).

I don't see a workaround.
Comment 5 rafschietekat 2010-04-26 16:40:32 UTC
Increased priority, if I may.
Comment 6 rafschietekat 2010-04-29 23:03:42 UTC
And I guess you can ignore that because I see this is about Scala, not C++...
