I got behavior like this from xscanimage when I linked it against<br>
|
||
gtk+970925 (before David sent the recent patch - I haven't patched the<br>
|
||
gtk yet.) But:<br>
|
||
<p>
|
||
1) It only bombs when xscanimage is started in the background<br>
|
||
(i.e. "xscanimage &" from the prompt, or selecting from the gimp<br>
|
||
menus.) If I do "xscanimage" from the prompt and keep it in the<br>
|
||
foreground, I still get the message about gtk_real_widget_queue_draw,<br>
|
||
but the program runs fine.<br>
|
||
<p>
|
||
2) I didn't get this behavior when I linked it against an older gtk<br>
|
||
(from gimp 0.99.10, w/ David's patches)<br>
|
||
<p>
|
||
3) This is on my system at home, which has a Umax Astra 600S. On my<br>
|
||
system here, which has a Color QuickCam but no Umax scanners, it works<br>
|
||
every time.<br>
