[maplab-users] Confusion over map redraw during query[Scanned]

Hi Zak,
I couldn't see any error messages that appeared relevant. I tried what you suggested, removed all the layers, trying the map with one layer at a time and the problem still occured.
I am a bit confused about the extents- when I run the shape files and rasters in Arcview I get the extent 0, 0, 70000, 130000 which is correct for the British National Grid. That's what the extent is set to in my map. But the extent shown in the MapBrowser box is the extent for the frame, which appears to put the rectangular map in the centre of the square and pad it to either side. If I set the map frame to be the same proportions in pixels as the map size is in metres, ie 700 wide by 13000 tall (or sensible fractions of these) then it still puts the map right in the centre, it doesn't make it fill the frame, which is what I thought it would do.
When I query the map and it redraws very small, the extents and scale shown below the frame don't change from what they should be if the map was drawn correctly.
Thanks again for your help
Jo

Hi Joanne,
If you bring up the error report (click on the yellow icon in the top
left of the window), is there any messages that looks relevant? The
next step I suggest is to completely remove individual layers from the
mapfile until the problem disappears.
Do the extents below the map image reflect the full extents of any of
the individual data files?

So basically if I'm in mapbrowser and I open the tutorial map and query it, there's no problem, if I open any of my other maps there's no problem, but if I open that one then the problem occurs. Interestingly, to test out whether there the problem happens with gmapfactory too, I have just made a new project using the same map, and the problem reoccurs then too.

I haven't got very much further with this problem, except to ascertain that it happens with only one map (attached and copied below). To recap: I am using maplab 2.2, with mapserver 4.4, and php 4.3.7. When using mapbrowser I load the map up and everything displays fine. Zooming and panning work fine. When I query a point on the map the query window opens and in the background the map is redrawn. When it finishes redrawing it is tiny and I have to recentre it or zoom out/in to make it redraw again, at which point it draws at the correct size. This happens whether or not I have rosa enabled. Any help would be much appreciated...
