*** IMPORTANT NOTE *** -> Before sending this message I downloaded and tried the 2.25.00 On this version the reported error does *not* happend. So I switched to the new version (hope everything else is OK too) I send this message only for informing people who could get the same problem. *** *** Hi, I got the following error when trying to use the mouse to change the dimensions of the default canvas created by the opeing of a 2D histogram : Error in <RootX11ErrorHandler>: BadValue (integer parameter out of range for operation) (XID: 0) I saved the canvas with the command 'save as canvas.root' so that I reproduce the problem on my system by doing : $ /bin/nice -5 root -n // -n so that I'm sure I dont load anything that could interfers... * Version 2.24/05 16 May 2000 * Compiled with thread support. root [0] TFile *f=new TFile("c1.root") root [1] c1->Draw() // here I use the mouse to change the dimension of the canvas by draging // one of it's side. (has to be done 2 or 3 times, quite fast) root [2] Error in <RootX11ErrorHandler>: BadValue (integer parameter out of range for operation) (XID: 0) Things that may be of interest (or not) : - Root is version 2.24/05, I didnt recompiled it - uname -a : Linux ganp188.in2p3.fr 2.2.13-22mdk #1 SMP Fri Oct 22 02:06:33 CEST 1999 i686 unknown (note this is a single processor machine, dont ask me why smp is enabled). - window manager : icewm-0.9.48-1mdk - version of X is : XFree86-3.3.5-3mdk (matrox millenium II SVGA driver) - Hardware is a HP vectra PC (Pentium II) => I put the file 'c1.root' I used on : http://www.feelingsurfer.net/garp/c1.root It can be retrived by http (the file size is less than 30kb). What I dont understand is that I already worked from some times with this version of root without seing this error message. I restarted my X server, but it didnt changed anything. Maybe there's something wrong in the histogram format on disk, but as I saved it again in it's own file it should have been rewritten properly, I think. Anyone has an idea ? Yannick
