This bugs depends on the version of Riched32.dll, which comes with the Windows operating system. It appears in conjunction with Riched32.dll dated Dez.14.96, on systems with the older Riched32.dll dated Sep.5.96 all works fine. In some cases a file may be opened two times, because the TeXShell can't distinguish between DOS and Windows file names which may be different for the same file. From version 0.51 you may be running into trouble if you are using programs that rely on Unix style pathnames with slashes instead of a backslashes. If such programs are still in use, please send a mail and we will provide you with the appropriate placeholders to call them from within the texshell.
Syntax highlighting is far from complete, but allready very usefull.
Please don't use automatic line breaks when editing text. This feature is only included to help you reading files with long lines. Long lines can cause some TeX configurations to crash. Also the line numbers that TeX use won't be the same as in the edit window. Don't forget to activate the network option in the ini file if you use the texshell in a network environment.
