The 1.1d is the latest version - the recent b, c and d version contain very minor changes that will not affect the majority of users. The changes are;
1.1b - we fixed the TIFF export that was broken on the (a) version
1.1c - slight change to way the movie player integrates with future XPE versions
1.1d - slightly altered start screen for trial versions
- a fix to the on screen separations view of blends
- a fix to copy / paste of XPE edited bitmaps from Xara X into other apps
- if you switch off web colours on the colour line this is now remembered

So this does not contain a fix for Richard's start-up problems. To my knowledge this is not something anyone else has reported or we've been able to reproduce and so we must assume it's something specific to his computer / configuration. A re-install of Xara X is probably the best thing to try. Customer support is advising.

For those that want to update to this version a patch is available for download from http://xara.com/downloads/xarax/
