OS/2 4.52 Japanese
PMView Pro 3.24 I've a crude REXX script that helps me write PPWizard headers for home page generation. When I drop a JPEG file on it, it calls PMView to do the file resizing and save. It is supposed to: copy a file to the tmp directory, Create a PMView script there opes the file with PMView and save it resized in another directory. There is about 148 MB worth of free space on the disk, but now and then I get the following error message: Unable to write file F:\sagyo\workshop\source\..\text\images\report\mb5h0087.jpg (Check that the file or disk is not write protected and that there is free space on the disk) I suspect PMView involvement because the right panel of the "Confirm file replace" which appears if I copy a file to the target directory shows a black image.. However, although it has worked reliably until today, it is also possible I've somehow messed something up in the script. I include it below in case someone should have the time & inclination to check whether I'm missing something glaringly obvious...

OK. Calling syssleep 1 before pmview may be the solution. I'll need to play around a bit more to be sure, though.
