The View menu at the top of the Detailed Form Editor allows you to set the following options:
Turn on or off the Auto Refresh. This option is enabled by default. When turned on, the form will refresh automatically each time a change is made. If this option is turned off, you will not see the visual impact of your form changes until you turn the AutoRefresh back on, or click the Refresh button on the Detailed Form Editor Toolbar. This may be useful when creating large forms with multiple fields as the time it takes to re-render the form may hamper your ability to quickly edit field data.
Change your screen resolution to 800 x 600, 1024 x 768, or 1680 x 1050. This useful feature allows you to see how your custom forms will appear to end users with different size computer monitors. When designing forms, you should take into consideration that some users, particularly those in the field, may have lower resolution monitors than those in the office.
