Hi,

It seems that there is a problem with mathematical input in maxima session in texmacs-1.0.7.2.

I start texmacs, open maxima session and switch on mathematical input. Any input e.g `a:1' results in `?' output. Terminal output:

$ texmacs --debug-io
TeXmacs] With linked TrueType support
TeXmacs] Launching 'tm_maxima 5.13.0 gcl'

This is a development version of Maxima. The function bug_report()

A new prompt `(%i1)' appears below, cursor stays at the old one. The first `(%i1)' produces only '?', but the second `(%i1)' works fine.

If I don't turn on mathematical input, no problem appears even with `(%i1)'.

Version info:
Ubuntu 8.04 Hardy
Maxima 5.13.0
