<h2>11.3 Problems with emulation on Windows</h2>

<p><em><strong>Q</strong>: My program which uses floating-point math hangs on Windows DOS
box when I try to use FP emulation<small>...</small>.</em>

<br><p>
<p><strong>A</strong>: This is due to a bug in the emulator in DJGPP v2.02 and earlier. 
The bug affected those programs running on Windows 3.X and 9X which use
the <small>WAIT</small> and <small>FWAIT</small> instructions (most of non-trivial FP
programs do), both those which use the emulator <code>emu387.dxe</code> and
those linked with the emulation library using the <code>-lemu</code> switch. 
The bug is solved in DJGPP versions 2.03 and later, so upgrade.
