Issue
When I/NET is running under Windows 7, there will be a display issue about alignment. The font size has been changed to smaller - 100%, but still no use.

Cause
Be sure to try I/NET Seven Windows fields not aligning correctly on workstation's display to change the font size first to see whether it can help. If not, continue to the next information.
I/NET used the default MS Sans Serif font to display everything. But something has changed in Windows 7 about the font display.
Research showed that many users with high resolution monitors (particularly LCD flat screens) were running the monitors at lower resolutions than the native resolution of the screen. This was usually because at the native resolution, the fonts were becoming too small to read, so the users would decrease the resolution.
Windows includes a facility to increase font and window sizes while keeping the screen at the native resolution. This is a much better method of increasing the font size as it can produce much smoother images by using many more, smaller pixels. The really significant issue is, unlike CRT monitors, flat-panel LCD monitors have a fixed pixel size, or "resolution", and that when users change to a lower resolution (in order to increase text size) the system has to re-sample the lower-resolution display image into its fixed resolution causing a significant degradation in display quality: not just text looks worse, everything looks worse.
A change was made for Windows 7, to set the screen resolution to the monitor's native resolution and if the screen is over a certain resolution to default the font size 120 DPI (dots per inch). This is approximately 125% of normal 96 DPI (100%). When the system defaults to 125% DPI it also adjusts the MS Sans Serif font to be bigger. If the user then decides to set the DPI back to 100%, then TrueType fonts, which are scalable, adjust as expected. But the bitmap MS Sans Serif font does not: it remains at the larger size, hence this issue. This problem does not occur if Windows 7 keeps DPI at 100% when it is first installed.
So anyway, when the default font size is Medium - 125% instead of smaller - 100%, probably the solution below is needed to solve it.
Resolution
- Go to the Registry Editor, and find HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts.
- Find the entry MS Sans Serif 8,10,12,14,18,24. The original value is set to SSERIFF.FON on a system which started at 125% DPI. Set to SSERIFE.FON on a system which started at 100% DPI. Notice that one character of the file name changes from F to E.
- Restart the computer, and make sure the font size is set to smaller - 100%. Refer to I/NET Seven Windows fields not aligning correctly on workstation's display about how to set font size. Then it should go back to work.
