Hi,there's a problem with the AG_Console where it can become impossible to scroll down far enough to be able to read the last line. This seems to be related to the '_' character being present in the console messages. This seems to happen with sdlfb and sdlgl only. The attached code illustrates the problem and the screenshot shows what the result looks like. The console contains 30 lines in the screenshot, but the last readable line is line 29. The screenshot was generated by running ./console-bug -d sdlfb. I submitted this to bugzilla #172.
