           Summary: Double-click zoom button causes GSView to display blank
                    page
           Product: GSview
           Version: unspecified
          Platform: PC
        OS/Version: Windows 98
            Status: UNCONFIRMED
          Severity: normal
          Priority: P4
         Component: General
        AssignedTo: gsview at ghostgum.com.au
        ReportedBy: goldart.geo at yahoo.com
         QAContact: gs-bugs at ghostscript.com


When viewing files such as alphabet.ps, colorcir.ps, escher.ps, grayalph.ps,
snowflak.ps, vasarely.ps, waterfal.ps from Ghostscript distribution, or
twopages.ps bundled with PSTOEDIT, Ghostscript shows a completely blank page
after pressing zoom or unzoom toolbar button again, before GSview completes the
ongoing zoom operation.

After the page goes blank, document window remains empty until the document is
reopened.
------------------------------------------------------------------------
Ghostscript version (or include output from "gs -h"): 8.62
------------------------------------------------------------------------
Where you got Ghostscript: Ghostscript.com
------------------------------------------------------------------------
Hardware system you are using (including printer model if the problem
involves printing):

Memory: 384MB
CPU: Intel Pentium II 400
Sound: ESS Solo-1
Video: Neomagic MagicMedia 256AV
------------------------------------------------------------------------
Operating system you are using: Windows 98SE
------------------------------------------------------------------------
Suggested fix, if any:

GSview must not draw blank pages when user readjust zoom setting before current
zoom readjustment is completed. Instead, GSview should restart the zoom
operation with new zoom setting.
