I got 5.90/5.91 working but found a problem with FastIPrefs 40.36b its DOpus5Patch. Without DOpus starts. If you want to check this out get it from aminet.
I want like to know which modules (e.g. parent.module), Scripts, tools (e.g. the xad stuff), ... is replaced by 5.90+ or isn`t needed more. Would help in merging versions together. The recommend use 5.90+ as basis isn`t good.
Havn`t checked ViewFont but I always missed the possibility to change font text color and maybe background color.
