1) This could be because of things like:mscim qimsys T9 keyboard portrait keyboard A manual removal of the packages one by one and testing in between might be able to resolve it and once resolved you can try reinstalling them until you find the culprit package. Once the culprit package has been found you can decide on what to do. (edit) I have had the virtual keyboard working flawlessly on the same CSSU version as yours so this is definitely not the issue with CSSU. 2) Conversation does not work in portrait mode, it has not been enabled in CSSU. So its not only you that is affected. 3) Try running conversations through command line and see if it spits out any errors.
