Message-ID: <780042@hpvcfs1.HP.COM> Date: 16 Aug 89 18:27:09 GMT References: <18981.24E12EE5@cmhgate.FIaONET.ORG> Organization: Hewlett Packard, Vancouver, WA Lines: 28 I know that I probably shouldn't post this, but this problem has come up several times recently... DeskWriter currently has a problem when printing with DeskPaint from Zedcor. This is caused by Zedcor passing an unlocked handle to the printer driver (any driver, not just DeskWriter). The problem occurs because the DeskWriter driver requests that the system clean up memory before it prints. The system complies and very neatly trashes the unlocked handle. It is not possible to remove the request from the DW driver, since performance is HIGHLY dependent on available memory. Zedcor probably needs to lock the handle before passing it to the driver. To get around the problem, you can use ResEdit to modify the DeskPaint DA and application. Simply open the file(s), find the Tprt resource (only one is present) and Get Info about this resource. The purgeable bit will be set... turn it off. Save the file and this should fix the bombing problem. Be sure to work only on a copy of the Zedcor files. Perform this modification at your own risk. It has not been extensively tested to determine if any nasty side effects occur. Some testing seems to indicate that the problem is fixed, but again, THIS IS NOT A SUPPORTED FIX by either HP or Zedcor. Disclaimer: I do work for HP and I did work on DeskWriter. However, these modifications are not endorsed by HP (have I said that enough?! :-). Rick Klaus hplabs!hpvcfs1!rickk
