Problems with Data Types, Medium Severity 7

	Change	Effect
1	Value of member LXW_ERROR_IMAGE_DIMENSIONS has been changed from 25 to 26.	Applications may execute a wrong branch of code in the library and therefore change the behavior.

	Change	Effect
1	Field url_rel_index has been added at the middle position of this structural type.	Layout of structure fields has been changed and therefore fields at higher positions of the structure definition may be incorrectly accessed by applications.
2	Field url has been removed from this type.	Applications will access incorrect memory when attempting to access this field.

	Change	Effect
1	Field theme has been added at the middle position of this structural type.	Layout of structure fields has been changed and therefore fields at higher positions of the structure definition may be incorrectly accessed by applications.

	Change	Effect
1	Field xf_id has been added at the middle position of this structural type.	1) Size of the inclusive type has been changed. 2) Layout of structure fields has been changed and therefore fields at higher positions of the structure definition may be incorrectly accessed by applications.

	Change	Effect
1	Field max_url_length has been added at the middle position of this structural type.	1) Size of the inclusive type has been changed. 2) Layout of structure fields has been changed and therefore fields at higher positions of the structure definition may be incorrectly accessed by applications.

	Change	Effect
1	Field default_url_format has been added at the middle position of this structural type.	1) Size of the inclusive type has been changed. 2) Layout of structure fields has been changed and therefore fields at higher positions of the structure definition may be incorrectly accessed by applications.
