Users of Windows 95 and 98 (including SE and ME), known collectively as "Win9x", see a slightly different version of PlansPlus than do users of the NT-derived Windows versions - Windows 2000 and XP. All versions of Windows use a drawing package called GDI to draw lines and figures on the screen. The version used in Win9x is derived from older "16 bit" code and therefore has less accuracy than the more modern versions that use "32 bit" drawing measurements. This difference causes the need to make a tradeoff between high resolution and the ability to cover large distances in drawing when using Windows 9x.
As opposed to what NT users see, Win9x users will see that lines used on the drawing (like dimension lines) have a thickness that becomes visible as more than a hairline when they are zoomed far in - that is, when the scale ratio is low. Note that this resolution thickness is expressed on the screen drawing, printing and exports only - it does not affect the accuracy of the measurements, which extend to 6+ decimal places in all cases. Once you are zoomed out to a scale of 1:24 or larger, then the screen results will be the same as they are for XP users.
The reason for this lack of fine resolution is inherent in the operating system, not a deficiency in Punch! or PlansPlus, or even in the hardware. Upgrading to Windows 2000 or to XP will alleviate the condition.
