Select the button "Break" and see what line of code the debugger places you
on. You might want to post that code if you still don't see what's
happening.

It sounds like this might clear it up for you:

public class Externs {
private Externs() {
}

// used to reset FP register to default state as per
// http://support.microsoft.com/default.aspx?scid=kb;en-us;326219
// If FPR not in default state initing fonts in controls can fail.
// _CW_DEFAULT should be the first arg, and 0xfffff the second
[DllImport("msvcr70.dll", CallingConvention = CallingConvention.Cdecl)]
public static extern int _controlfp(int n, int mask);
// definitions taken from FLOAT.h
public static int _CW_DEFAULT =
0x00000000 + 0x00000000 + 0x00000010 + 0x00000008 + 0x00000004 + 0x00000002
+ 0x00000001 + 0x00080000; //( _RC_NEAR + _PC_53 + _EM_INVALID + _EM_ZERODIVIDE
+ _EM_OVERFLOW + _EM_UNDERFLOW + _EM_INEXACT + _EM_DENORMAL)
}

Use it somewhere in your startup before creating the form as so:

Externs._controlfp(Externs._CW_DEFAULT, 0xfffff);


HTH!
