If you're working on a large document and you request to "generate backup files" (see Preferences), that could increase delays. > I am always erasing characters that I don't intend to erase.

Yesterday we found out a case where this occurs, perhaps it's the case you want to mention: When setting the cursor at the end of a word and deleting characters with backspace, including the space before the word, the last character of the previous word is deleted. This is due to a strange interference with the algorithm that repairs consecutive spaces as specified in HTML. We're are fixing this problem. > Furthermore, the scrolling in Amaya is so jerky that I often have > to try several times before I can get the browser to window the portion of > the document that I need to work on. Amaya formats only a partial view of the document. This is necessary to limit the reformatting when you insert characters. So a scroll to another position can skip to a not already formatted position, and that explains the jerky response. > Unfortunately, simple things like > keyboard response are often more important than an extensive feature set if > one has to use the tool to produce product. > > Many things about Amaya appear to be really well thought out so I am > surprised that it doesn't get the fundamental editor stuff right. > > PS: I am working on an SMP machine. I don't know if that might matters. The most important is the performance of the OpenGL implementation as Amaya 9.x are based on this technology. > PPS: I have managed to put Amaya to useful work.
